Level of toxicity: Generally mild to moderate, depending on the amount ingested and if ethylene glycol is present
Common signs to watch for:
- Severe sedation
- Stumbling
- Seizures
- Tremors
- Panting
- Disorientation
- Lethargy
- Metabolic acidosis
Propylene glycol is one of the least toxic glycols. It is a synthetic liquid substance that absorbs water and is used by the chemical, food, and pharmaceutical industries for a wide variety of reasons. Like
ethylene glycol, propylene glycol may be used as an antifreeze and can be found in high concentrations in RV and “pet safe” antifreezes. Since it has a wider margin of safety as compared to its chemical cousin, ethylene glycol, it is commonly used to absorb extra water and maintain moisture in certain medicines, cosmetics, or dog and human food products and is categorized by the FDA as a GRAS (generally recognized as safe) substance for this use. It is also used as a solvent for food colors, flavors and pharmaceuticals (i.e. injectable diazepam). Cats are particularly sensitive to PG and its use is not allowed in cat foods. Historically,
some semi-moist cat foods contained up to 5-10% PG and cats were harmed by this (Heinz body formation).
If cats or dogs ingest large amounts of propylene glycol, poisoning can occur. This is most commonly seen when pets ingest liquid propylene glycol products.
Poison type: Garage Items
Alternate names: Pet-safe antifreeze, PG,

So let's break this down a bit. Avg cat: 6 oz semi-moist food per day. (such as tender vittles) 6oz = aprox 200ml (volume) x 5% = 10ml. Say for maximium effect.. 50/50 pg/vg blend. SO.. 5ml pg per day. pg mixed with 5ml vg for 10ml vape juice. 10 ml is a whole bloody lot. But, lets say someone is using a dripper and actually does use that much.
You would literally have to put your cat in a box, but the box in a garbage bag and blow vape fog into the hose for the entire day, to get even close to 5ml pg into the cat. Now considering a small box, 12x24x12 (just barely big enough for a cat, and much bigger than your lung capacity) you would have to be vaping pretty hard and fast to get close to 5ml of pg into that cat.
Now also, given that we don't do that, and the actual volume of fog as parts per million in a full vape cloud.. that cat could literally stand in front of you all day tap dancing in your fog and never come close to 5ml of ingested pg.
Also remember...
depending on the amount ingested and if ethylene glycol is present
If you are vaping ethylene glycol, the cat is the least of your worries. You'll be in a coma long before that cat even sneezes.
In other words, you can vape til you turn purple and that cat wont even twitch.. just don't feed it vape juice straight from the bottle.
Now, if the cat starts building coils and stealing your mech mod, then I would worry. Cat's have a hard time calculating ohms law.. its hard for them to hold a pencil with those little tiny 'fingers'.
Get someone that smokes to blow smoke in your cats face... the cat gets up and leaves, right? Blow vape fog at the same cat, and he is more likely to watch it drift by and stare at you waiting for you to do it again.
Can you imagine how many fog rings a cat would have to chase down and bite into to get 5ml of pg?
